The 'SR' prefix indicates its bass nature & its overall outline is indeed reminiscent of a typical Ibanez Soundgear (SR) bass. However, the manufacturer reckons the addition of a high E string in there makes this a 'hybrid' instrument; something capable of churning out the bottom end frequencies as well as enabling the player to break into solos...
Default tuning (low to high): B-E-A-D-G-C-E
Significance: An innovative release by Ibanez, it's still in its proto stages so seeing one in stores would take time. I'd say it'll catch on with the bass dweebs more so than the guitar slingers due to its bass scale length.
Concern: As depicted, the instrument features a stressful string break angle from the nut to the machine head (especialy so for the ones at the extreme ends) & this would affect tuning effectiveness (friction related).
